- Candy Chromatography
(Ages 3-16)
With Valentine's day quickly approaching there has been a lot of talk about what kinds of sweet treats we will be giving out to friends. M&Ms are a favorite in our house so I was pleasantly surprised to learn that they can also be used to teach lessons on chromatography! Find out how the candy gets to be the color that it is with this super simple experiment! We used M&Ms, but try different candies, like Skittles or jelly beans.

Harness the power of fizzy candy and soda to inflate a balloon without blowing! This experiment can be repeated many times with different sodas to see how each reacts differently and which creates the biggest balloon.

5 Halloween Candy Science Experiments for Kids
Halloween candy gets a second life as a science lab. Each mini experiment shows off a different piece of science, from diffusion to crystal growth. Three of them start with candy you probably already have after Halloween. Ages run from 3 to 16 depending on the project, and two of them need a grownup at the stove.
